' HEATER FOR MOTOR CARS.

Application filed December 24, 1924. Serial No. 757,797.

To all whom-it may concern:

Be it known that 1, CHARLES B. WATERS, a citizen of the United States, and a resi- -dent of Montclair, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Heaters for Motor Cars, of which the following is a specification.

The invention relates to motor car heaters adapted for heating the interior of, a motor car or self-propelled vehicle; and it has for its object means for accomplishing this in a simple and eflicient manner to afford the proper degree of warmth and without the usually attendant objectionable odors. A further object of the invention consists in a heater which will continue to function for an appreciable time after the. shutting down of the motor of the said vehicle. A still further object of the inventiomresides in a device of this character which will entail no appreciable loss of power and the use of which, as a matter of" fact, is beneficial 'to the operation of the motor.

Further objects are a rugged and readily quickly'installed device, requiring but tion. a

The nature of the invention, however, will best be understood when described in connection with the accompanying drawings,

" in which-- Fig. 1 is a fragmentary elevation illustrating the motor and radiator of an internal combustion engine, a portion of the body of the self-propelled vehicle and. the novel heating a paratus secured in position.

Fi 2 is a etail longitudinal section of the tting member employed; and Fig. 3 is a transverse section thereof taken on the line 33, Fig. 2, looking in the direction of the arrows.

'Referring to the drawings, 10 designates "an internal combustion engine of any wellknown or s therewith t e usual water cooling system including a radiator 11 and a pipe connection 12 between said radiator and the water ial type and having associated essentially of a short length of piping to the ends of which are adapted to be connected the corresponding ends of the said connection 12 between radiator and internal.

combustion 'engine and which is generally in the formof a flexible hose member. As is the usual practice, the connection 12 is inclined from the engine 10 to the radiator 11 with its lowermost end at the engine portion, and the fitting 13 assumes substantially the same angle of inclination. Moreover, in accordance with the usual practice, the cooling water is circulated between the radiator and engine as by means of a pump 14, and passes upwardly thru the connection 12 and thus also thru the inserted fitting 13. Preferably, along the lower or under surface of this fitting, ta s are provided as at 15 and 16, the former being at a lower level than the latter and each being provided with inwardly projecting fins or blades 17 and 18, respectively. The former blade 17 is bent. downwardly and in a direction to oppose the incomin stream of water while the blade 18 is also ent downwardly but in thereverse direction with reference to the fitting, that is to say, in the direction of flow thru said fitting and reduces somewhat the aperture.

From the taps 15 and 16 thus provided, connection is made, as by means of corresponding hoses or pipes 19 and 20, to a radiating member 21 which may be placed at any convenient location along the floor of the car to suit requirements. Any suitable form of radiating member which will permit of circulation of water therethru may be employed; and there is inserted in the incoming line 19, a valve 22 for controlling the supply. This valve will be located convenient y for control by the operator of the car so that the heat afforded by the radiating member 21 may be'varied as desired.

In operation, a portion of the heated water passin thruthe fittin 13 will be diverted by t e fin or. blade 1 thru the tap 15 and hose 19 to set up a circulation, when valve 22 is open,'thru the heat-radiating member 21 and back thru the hose 20 to the tap 16. It will be .noted that the fin or blade 18 forms a more. or less constricted aperture at the tap 16 which, in conjunction with the velocity of the stream priming upwardly thru the fitting 13 and past the said aperture, will tend to provide an ejector action to further induce circulation thru the connections 1920.,

By the expedient hereinbefore described, a circulation of comparatively hot water y be maintained to provide the desired degree of warmth in the car; and it will be appreciated that, as water retains its heat for a considerable period, the stoppin of the engine will not immediately shut o the supply of heat as is the case with heating devices receiving their supply of heat from the exhaust of the engine. Moreover, there is no danger of objectionable odors from the exhaust entering the car thru the use of the novel heating device, and there is no loss of power involved in its use. As a matter of tact, additional radiating surface is thus provided to assist in the cooling of the circulating liquid which in some motors has a tendency to become overheated. The installation of the fitting, furthermore, is an extremely simple matter as it is n merely to replace the usual hose connection 12 between engine and radiator by a connection including the said fitting and then.

make the necessary connections to the radiating member 21.

I claim 1. In combination with a water cooling system, a hot water heating system comprising means for diverting part of the Water from said cooling system under a circulating pressure built u by the velocity of flow of the water in sai cooling system; a radi ating member disposed below said diverting means; a feed conduit connecting said d1- venting means with said radiating member; means disswed above said radiating memjacent said diverting means for aerate? 2. in combination with a Water cooling system for an engine, an outlet opening for diverting part of the heated Water from the cooling system at a point above the engine; a defiwting lip over said outlet opening; a radiating member disposed substantially below said outlet opening; a conduit connecting said outlet opening with said radiating member; a return opening for the diverted water at a point above said outlet opening in said cooling system; a deflecting lip over said return opening; and a conduit connecting said radiating member with said return openi, t

3. In combination an internal combustion engine, a water cooling system therefor comprising a cooling radlator and a force feed pump; means interposed between said engine and said coolin radiator for diverting a part of the circu ating water from the coolin system under the ve ocity of flow of t ewater in the cooling system; means interposed between said diverting means and said cooling radiator CHARLES E.
